Combined with the carbonate reservoir characteristics as large gas rate,viscous crude and produced naturally,this paper regressively analyzes and matches the dynamic liquid level,submergence depth, pump efficiency ,water content,oil density and viscosity of 137 sucker rod pump wells.

针对塔河油田机抽井的沉没度大大高于中国石化平均水平的现状，结合塔河油田碳酸盐岩油藏气大、油稠、依靠天然能量开采的特点，对正常生产的130口有杆泵井的动液面、沉没度、泵效、含水、原油密度、原油黏度等数据进行了回归分析和拟合，给出了不同含水期、不同日产液量的机抽井合理沉没度范围。

However, these rigid and dense carbonates and thick-bedded sandstones are of relatively developed secondary fractures and solutional pores, which are mainly distributed in four suites of rigid rocks.

然而对于刚性致密的碳酸盐岩以及厚层块状砂岩，次生裂隙、溶隙相对发育，它们分布于四套主要的刚性岩层中，极大地改善了这些岩石的孔渗性能，使之成为良好的裂隙储集体，为海相中生界、古生界油气聚集成藏提供了有利的储集空间。

So brachiopods as indicators of original isotopic compositions of marine limestones is undoubtful.

因此从本论文的研究看，腕足化石作为碳酸盐岩原始氧、碳同位素研究的较为理想的样品不应受到怀疑。

The complicated oil field of karst cave and crack are controlled by limestone reservoir and the crevices-cave system, which have many characteristics such as vivid and great in style, irregular distribution, the limestone cave in crack and unhomogeneity of rock etc.

笔者力求充分利用各种开发生产的动态信息，探索研究和评价储层特征的方法及思路，主要研究成果如下：(1)结合塔河油田动静态分析和实践，将缝洞型碳酸盐岩油藏划分为三类组合模型：缝-洞系统、双裂缝系统和缝孔系统。

However, as a result of its rather lower porosity, unhomogeneous medium and anisotropy, the exploration procedure faces more amd more difficulties, especially the high request and some new challenges are required for current log method and its interpretation technique, and prompts the ordinary log interpretation to develop toward modern fine interpretation.

然而由于裂缝性碳酸盐岩储层所特有的低孔、非均质性和各向异性，大大增加了油气勘探开发的难度，尤其对目前的测井方法及其解释评价技术提出了更高的要求和新的挑战，促使测井解释由原来的粗放型向现代精细评价方向发展。

In addition, a quantitative analysis of factors influencing the cavern imaging accuracy in the traditional and new methods provides a theoretical guide to improve the exploration accuracy of vuggy carbonate reservoirs.

同时，对常规偏移成像方法和逆散射成像方法影响溶洞成像精度的主要因素进行了定量分析，为提高溶洞型碳酸盐岩油气藏勘探精度提供了理论指导。图11参23

Skelton highlights the water vapour and oxygen transmission rates, its unsuitability for carbonates and the fact that it deforms at high temperatures.

skelton突出了水蒸汽和氧气的传输速率，它不适合为碳酸盐岩和事实，即它变形在高温下。
