【摘要】：國內(nèi)水平井用油基鉆井液普遍存在切力低、流變性能差和后續(xù)鉆屑處理難度大等問題,在性能和環(huán)保方面均需要完善。為滿足綠色高性能鉆井液的發(fā)展需求,以天然來源的植物油為原料,采用生物和化學(xué)改性的方式,合成了一種性能優(yōu)異、可生物降解的生物質(zhì)基液PO-12。性能測試表明,PO-12具有黏溫特性優(yōu)良、穩(wěn)定性好、抑制性強、抗水解和無熒光的特點,其結(jié)構(gòu)中不含芳香基團,無毒,綠色環(huán)保,能夠滿足水平井和深海鉆井需求。以PO-12為連續(xù)相,初步形成一種生物質(zhì)合成基鉆井液,性能與油基鉆井液相當(dāng),為提高水平井用鉆井液的綠色環(huán)保性能提供了一種新的途徑。
[Abstract]:In China, the problems of low shear force, poor rheological performance and difficulty in subsequent drilling cuttings treatment are common in domestic oil based drilling fluids for horizontal wells, which need to be improved in terms of performance and environmental protection, in order to meet the development needs of green and high performance drilling fluids. Using natural vegetable oil as raw material, a biodegradable biomass based liquid PO-12 was synthesized by biological and chemical modification. It has the characteristics of anti-hydrolysis and non-fluorescence. Its structure is non-aromatic, non-toxic, green, and can meet the requirements of horizontal wells and deep-sea drilling. With PO-12 as the continuous phase, a biomass synthetic drilling fluid is initially formed. The performance of the drilling fluid is equivalent to that of the oil based drilling fluid, which provides a new way to improve the green environmental performance of the drilling fluid used in horizontal wells.
