The measurement results show that the general characteristics of the present crustal stress field of the project area are as follows: the horizontal principal stress is the maximum principal stress, and the preferred orientation of the maximum horizontal principal stress is NW-WNW, the maximum principal stress of surrounding rocks of the plant buildings and high-pressure branch tunnel area is generally 14.5±0.5 MPa and the minimum principal stress is 9±0.5 MPa; the dead oad-bearing capacity of surrounding rocks is 10—14 MPa; and the surrounding rocks are essentially impermeable at high pressures of 8—10 MPa.

测量结果表明，工程区现今地壳应力场的总体特征为：水平主应力为最大主应力，最大水平主应力的优势方向为NW-NWW向；厂房和高压岔管区围岩的最大主应力值一般为14.5±0.5MPa，最小主应力值一般为9±0.5MPa；围岩自身的抗载强度一般为10～14MPa；在8～10MPa高压力作用下围岩基本不透水。

A hardened soil horizon, usually in the middle or lower part of a soil profile, A hardpen is typical of PODSOLS, where iron compounds leached from the upper layers accumulate in the B horizon, staining it red-brown and forming an impermeable layer that can prevent drainage, resulting the in waterlogging of higher horizons.

硬质地层是一种典型的灰壤，其中铁的化合物从上层土壤中渗出，在 B 层中聚集，使得土壤呈现棕红色，构成了极难透过水的土层，这种地层的存在使上层的土层更易发生水涝。

3Based the trait of the vegetable gum drilling and completion fluid, used LV-CMC,FJ-03, polyglycol, JL-α and SMP-Ⅰas the filtration control agents which should be optimized. Finally this paper optimized LV-CMC and polyglycol as the filtration control agents. In order to form a tough impermeable cake, this paper used QS-2 as the inflexible filling material according to the mechanism of fluid loss control.

根据植物胶钻井液完井液的特点，确定LV-CMC、FJ-03、聚乙二醇、JL-α、SMP-Ⅰ为降滤失剂的优选对象，通过实验优选出LV-CMC、聚乙二醇为植物胶钻井液完井液体系的降滤失剂，并根据钻井液的降滤失机理，为使形成更加坚韧致密的泥饼，确定QS-2作为刚性填充粒子。
