摘要/Abstract

摘要： 临兴区块属于鄂尔多斯盆地东缘致密气藏，由于地层泥岩砂岩互层发育、储层低孔低渗、水敏性强、摩阻大，在钻井过程中普遍存在井壁失稳、储层伤害等问题，为此开展了该区块钻井液技术研究。在分析储层特性和主要技术难点的基础上，从“增强抑制、保护储层”角度出发，以双疏材料为核心处理剂，优选并建立了一种双疏型强抑制低伤害水基钻井液体系。使用的双疏剂可将低渗储层毛细管吸力反转为阻力，使岩石表面由亲液向疏液转变，同时该材料具有较好的润滑、抑制、封堵性能。双疏体系高温高压滤失量低于10 mL；滤饼薄而韧，黏附系数低至 0. 034 9；岩心渗透率恢复值大于90% ；可抗10% 氯化钠和 0. 5% 氯化钙污染。该体系在临兴区块成功应用，解决了现场井眼垮塌和反复回填的问题，保证了顺利施工完钻。现场试验表明，双疏体系性能优良，具有在临兴区块进一步推广应用的潜力。

Abstract: The Linxing Block belongs to tight gas reservoir on the eastern margin of the Ordos Basin. Due to the development of inter-bedded mudstone and sandstone, the reservoir exhibiting with low porosity, low permeability, and strong water sensitivity, and large frictional resistance, wellbore instability and reservoir damage are common problems in drilling. For this reason, the drilling fluid technology for this area was studied. Based on the analysis of reservoir characteristics and technical difficulties, and the perspective of " enhanced inhibition and protection of the reservoir" , an amphiphobic water-based drilling fluid with strong inhibition and low damage was optimized and established through adding amphiphobic material as the main agent. This amphiphobic material can reverse the capillary suction of low-permeability reservoirs into drag resistance, and transform the rock surface from hydrophilic to hydrophobic. Moreover, this material has good lubrication, inhibition and plugging properties. The drilling fluid showed a low HTHP fluid loss of less than 10 ml. The formed filter cake is thin and tough, and the adhesion coefficient is as low as 0. 0349. The core permeability recovery value is more than 90% . Besides, the drilling fluid can resist 10% NaCl and 0. 5% CaCl₂ pollution. The fluid was successfully applied in the LX well, which solved the problems of borehole collapse and repeated backfill, and ensured the successful operation. The field test shows that the amphiphobic water-based drilling fluid has excellent performance and has the potential for further promotion in Linxing Block.

Key words: water-based drilling fluid, amphiphobic agent, inhibition, reservoir protection, Linxing Block
