On the base of the brief description of the drive and control system of micro-fluid and the experimental setting of the technology of micro-injection, a novel process of the hydrophobe treating used to mend the characteristic of the inner and outer surface on micro-pipette is designed, which can improve greatly the injected effect and eliminate the disadvantage such as seepage or regurgitation during injection. The author puts forward the way of measuring the inside diameter of the micropipette. The program of measuring micro injection amount is designed. The original data of the micro injection experiment are explained and interpreted at last in the thesis.

Data pre-processing technologies such as singular points elimination, registration and radius compensation are studied. Base on chord high difference algorithm, a new one called chord high difference-ratio algorithm is proposed to improve veracity and robusticity of singular points elimination. Then, a registration algorithm based on local surface reconstruction is proposed, which avoids infaust influence coming from single reference point error.

Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.
结合已有的研究资料可以认为,黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质,浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质;含铁建造形成于陆壳基底之上,形成时间约2.7 Ga,并于2.5—2.7 Ga之间发生首次变质作用。

In this paper, the characteristics of reservoir of reservoir of delta frontal sub-faces of PI Formation in the south of Xingshugang are studied with the data of dense well pattern and rock-mineral identification. The delta frontal sub-faces can be divided into lobate delta frontal sub-faces, branched delta frontal sub- faces and sheeted delta frontal sub-faces. The genetic types of sand bodies in different sedimentary envivonments are analyzed in detail, and the distribution and space-matching relationship of different sand bodies are studied. The micro-pore structure type is studied on the base of the thin section analysis, so the reservoir heterogeneity is studied including plane heterogeneity, interlayer heterogeneity, in-layer heterogeneity and microcosmic characteristic.
