When the flow through the balance of the piston damping the flow of holes increases, the balance of the piston, the next increase in pressure on both sides of a balanced increase in the distance the piston increases, and vice versa reduced; and also because the spring stiffness is very small, so that shift the balance of the piston pressure required very few changes, so the flow through the Poppet head is not much change, so the first opening Poppet very few changes, to mention the pressure of moving the first opening can be said to remain unchanged, that is, when the pilot valve spring after a set, Poppet Head was opened, the balance piston chamber pressure remained basically unchanged.
当流经平衡活塞上阻尼孔的流量增加时,平衡活塞上、下两侧的压差增加,平衡活塞上升距离增加,反之则减小;又因为弹簧的刚度很小,使平衡活塞上移所需压差变化很小,所以通过提动头的流量变化也不大,因此提动头的开口变化很小,提动头开启的压力可以说是不变的,亦即当先导阀的弹簧一经设定后,提动头被打开时的平衡活塞上腔的压力基本保持不变。

The reservoir rock types in the region of interest are grain limestone, algal limestone, cryptite, siltstone, muddy limestone and mudstone. The thesis identified as a result of changes in the deposition causing the heterogeneity in plane, and then the geological oil reserves have been calculated in accordance with the areal heterogeneity.3、Based on the data of core analysis, bore logging, array induction imaging log and FMI, porosity and permeability model were built using regression analysis. Through testing 45 rock samples, a, b, m, n value were obtained and used to calculate single-layer oil saturation value using the Archie formula. According to the theory of laterolog and inductolog, resistivity ratio and cross plot were used to identification effective thickness. Effective thickness was identified delicately in 103 wells. Based on the over work, active porosity and oil saturation was calculated accurately.4、According to observation of 100 pieces of the thin slices, cast thin slices and 383m core in three wells, the chief diagenesis in this area were compaction, cementation, denudation and cataclasis. Cementation and denudation were universally influenced active porosity this area.

And the conclusions were as follows:①The principal reason leading to oil distribution unequal is interior structural feature of reservoir in structural hydrocarbon reservoir.
