Abstract
The invention relates to a sealing fluid used for sealed coring during petroleum exploration, development and drilling and a preparation method thereof. The environment-friendly oil-based sealing fluid mainly comprises plant oil, plant resin and emulsifier with the mass ratio of 50-90: 5-20:1-10, and the environment-friendly oil-based sealing fluid is obtained by the following preparation method: the plant resin is uniformly dissolved in the plant oil containing the emulsifier between 90 DEG C and 140 DEG C and fully mixed to form the stable oil-based fluid. The environment-friendly oil-based sealing fluid is mainly used in coring operation of petroleum exploration, development and drilling.
Description
Technical field
Environment-friendly oil-based sealing fluid of the present invention and preparation technology thereof relate to the sealing fluid that sealing core drill uses in the petroleum exploration and development drilling process.
Background technology
At present, in the petroleum prospecting, the drilling well sealing core drill uses sophisticated sealing fluid to be divided into oil base, water base and synthetic basic three major types both at home and abroad.
Oil-based sealing fluid comprises two kinds of Viscotrol C oil-based sealing fluid and high effective sealing liquids.The Viscotrol C oil-based sealing fluid mainly is to stir refining at a certain temperature by Viscotrol C, supervinyi chloride resin and mono stearate glyceryl ester to form; But emit with toxic gases such as chlorine, hydrogenchloride in the process for preparation, contaminate environment, the infringement operator healthy, the product performance instability.The high effective sealing liquid main raw material is the viscous crude in the crude oil, and using this sealing fluid to core can be influential to the mensuration and the show of oil and gas (SO﹠G) well logging interpretation of oil saturation.
Water base sealing liquid comprises water base fine calcium sealing fluid, water base amine cyanines sealing fluid and aqueous-based polymers sealing fluid.Because the raw material of water base sealing liquid is formed, water base sealing liquid exists temperature resistance poor, Applicable temperature scope little (0 ℃～105 ℃), and cored interval is shallow, lacks the shortcoming of (5～90 days) storage period.
Synthesized base sealing fluid is that external phase, resin of plastification (polyethylene kind or polyvinyl chloride) make through series reaction for main film forming material, plugging agent (comprising lime carbonate, organophilic clay, sulfonated gilsonite, oil-soluble resin) and emulsifying agent by organic ester (Methyl Benzene-o-dicarboxylate class) mainly.This sealing fluid has starting material wide material sources, stable performance, environmental friendliness, to the advantages such as high adsorption capacity of rock core, but blending process is complicated, preparation temperature height.
Summary of the invention
For solving the existing problem that liquid exists of closing, the invention provides a kind of environment-friendly oil-based sealing fluid and preparation technology thereof.
Environment-friendly oil-based sealing fluid provided by the invention consists predominantly of vegetables oil, propolis and emulsifying agent.Its quality proportioning is 50～90: 5～20: 1～10.Vegetables oil can be one or several of soybean oil, sunflower seed oil, Rice pollard oil, tea oil and Semen Maydis oil; Propolis is a Gum Rosin; Emulsifying agent is sorbitan monooleate and oleic acid.
Above the preparation technology of described environment-friendly oil-based sealing fluid as follows:
Step 1: under the normal temperature state, with the even stirring and dissolving of emulsifying agent in vegetables oil;
Step 2: after the solution of step 1 gained slowly is heated to 90 ℃～140 ℃, propolis is added, fully stir, form stable oil based fluids.
The present invention compared with prior art has the following advantages: raw material sources are extensive, product performance are stable, blending process is simple, the Applicable temperature scope is wide and meet advantage such as HSE requirement.
Specific embodiment
The starting material vegetables oil of selecting for use in following examples is a soybean oil, and propolis is a Gum Rosin, and emulsifying agent is that sorbitan monooleate (SP-80) mixes with 1: 2 mass ratio with oleic acid.
Embodiment 1
Respectively take by weighing vegetables oil, propolis, emulsifying agent at 50: 10: 8 by the quality proportioning, wherein
Production technique is: (1) with the even stirring and dissolving of emulsifying agent in vegetables oil; (2) solution of (1) gained slowly is heated to 120 ℃ after, propolis is added, fully stir, form stable oil based fluids, promptly make environment-friendly oil-based sealing fluid.
Embodiment 2
By the quality proportioning is respectively to take by weighing vegetables oil, propolis, emulsifying agent at 80: 20: 10, wherein
Production technique is: (1) with the even stirring and dissolving of emulsifying agent in vegetables oil; (2) solution of (1) gained slowly is heated to 120 ℃ after, during propolis added, fully stir, form stable oil based fluids, promptly make environment-friendly oil-based sealing fluid.
Embodiment 3
By the quality proportioning is respectively to take by weighing vegetables oil, propolis, emulsifying agent at 75: 12: 6, wherein
Production technique is: (1) with the even stirring and dissolving of emulsifying agent in vegetables oil; (2) solution of (1) gained slowly is heated to 120 ℃ after, during propolis added, fully stir, form stable oil based fluids, promptly make environment-friendly oil-based sealing fluid.
Each embodiment performance comparison is estimated:
As can be seen from the above table, each embodiment product all reaches the sealing fluid requirement of coring among the SY/T5347-2005,
Wherein embodiment 3 effects are best.
