Description
Technical Field

Background
With the rapid development of national economy, the crude oil demand is increased, the external dependence of crude oil in China is high, the national energy safety warning line is seriously exceeded, the energy safety alarm is sounded, and the oil-gas self-sufficiency is urgently required to be improved. Land oil gas yield tends to be stable, and marine oil gas is an important oil gas take-over area in China in the future, wherein the oil gas reserves in the south China sea exceed 300 hundred million tons, and 70% of the oil gas reserves are in deep water areas.
Deep water jet method is adopted to realize exploitation of oil gas in deep water area. The deep water injection method uses an injection pattern to lower the conduit into place. The gravity of the water jet and the guide pipe string is utilized to spray the holes while the guide pipe is lowered, and meanwhile, the power drilling tool assembly is lowered into the spray pipe column to improve the safety and the operation efficiency. After the conduit is lowered to a predetermined well depth, the conduit string is stopped, and the conduit is stabilized by using the adhesive force and friction force of the stratum. And then releasing the running tool and lifting out the drilling tool in the catheter to complete the installation of the catheter.
However, the deep water injection method has the following problems:
1. the deep water injection method has complex tool and higher requirements on matched ships;
2. The deep water injection method is suitable for water depth within 1000 meters, and can not meet the drilling requirements of deeper depth;
3. The deepwater injection method utilizes water jet operation, is easy to damage stratum, increases drilling difficulty and is not beneficial to further petroleum development;
4. The deep water injection method needs well cementation, so that the operation links and time are increased;
5. When the intensity of the seabed soil is high, the situation that the deep water surface layer conduit is not sprayed in place is extremely easy to occur;
6. Because of the oscillation that occurs with jetting, when the well spacing is too small and the oscillation amplitude is too large, well "channeling" is likely to occur.

It should be noted that, in the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and to distinguish between similar objects, and there is no order of preference between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
Any numerical value recited herein includes all values of the lower and upper values that increment by one unit from the lower value to the upper value, as long as there is a spacing of at least two units between any lower value and any higher value. For example, if it is stated that the number of components or the value of a process variable (e.g., temperature, pressure, time, etc.) is from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, then the purpose is to explicitly list such values as 15 to 85, 22 to 68, 43 to 51, 30 to 32, etc. in this specification as well. For values less than 1, one unit is suitably considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples that are intended to be explicitly recited in this description, and all possible combinations of values recited between the lowest value and the highest value are believed to be explicitly stated in the description in a similar manner.
Unless otherwise indicated, all ranges include endpoints and all numbers between endpoints. "about" or "approximately" as used with a range is applicable to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30," including at least the indicated endpoints.
All articles and references, including patent applications and publications, disclosed herein are incorporated by reference for all purposes. The term "consisting essentially of …" describing a combination shall include the identified element, ingredient, component or step as well as other elements, ingredients, components or steps that do not substantially affect the essential novel features of the combination. The use of the terms "comprises" or "comprising" to describe combinations of elements, components, or steps herein also contemplates embodiments consisting essentially of such elements, components, or steps. By using the term "may" herein, it is intended that any attribute described as "may" be included is optional.
Multiple elements, components, parts or steps can be provided by a single integrated element, component, part or step. Alternatively, a single integrated element, component, part or step may be divided into separate plural elements, components, parts or steps. The disclosure of "a" or "an" to describe an element, component, section or step is not intended to exclude other elements, components, sections or steps.
It is to be understood that the above description is intended to be illustrative, and not restrictive. Many embodiments and many applications other than the examples provided will be apparent to those of skill in the art upon reading the above description. The scope of the present teachings should, therefore, be determined not with reference to the above description, but instead should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated herein by reference for the purpose of completeness. The omission of any aspect of the subject matter disclosed herein in the preceding claims is not intended to forego such subject matter, nor should the inventors regard such subject matter as not be considered to be part of the disclosed subject matter.
